Technical Field

[0001] This utility model relates to the field of railway locomotive technology, specifically to a railway locomotive traction rod anti-detachment device. Background Technology

[0002] Currently, the common cross-sections of railway locomotive drawbars are mainly circular or rectangular. Existing anti-derailment devices for railway locomotive drawbars are designed to connect with drawbars of either circular or rectangular cross-sections to meet different usage requirements. This method involves dividing the clamp of the anti-derailment device into two parts that connect to the drawbar and then locking them with bolts. However, this method uses too many bolts, making installation, disassembly, and maintenance very inconvenient. At the same time, the connection and installation between the inclined steel wire rope and the anti-derailment device is also very troublesome, resulting in low efficiency. Therefore, this application proposes an anti-derailment device for railway locomotive drawbars to solve the above problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figure 1-4 As shown, this utility model provides a technical solution: a railway locomotive traction rod anti-derailment device, including a connecting rod 1, with traction seat cylinders 2 connected to both ends of the connecting rod 1 via flanges, two anti-derailment devices 3 on both sides of the connecting rod 1, and a diagonal steel wire rope 4 on the anti-derailment device 3, with a locking strip 6 connected to the bottom end of the diagonal steel wire rope 4 and connected to the anti-derailment device 3, the joint on the top side of the diagonal steel wire rope 4 being rotatably installed on the car body connecting seat or the bogie connecting seat, the two anti-derailment devices 3 being used in pairs, one anti-derailment device 3 being installed close to one side of the traction seat cylinder 2 and rotatably connected to one end of the diagonal steel wire rope 4, the other end of the diagonal steel wire rope 4 being rotatably connected to the car body connecting seat; the other anti-derailment device 3 being installed close to the other traction seat cylinder 2 and rotatably connected to one end of the diagonal steel wire rope 4, the other end of the diagonal steel wire rope 4 being rotatably connected to the bogie connecting seat, thereby preventing detachment by tightening both ends of the connecting rod 1, thus avoiding safety hazards or major safety accidents, and a limit device 5 being provided on the bottom side of the anti-derailment device 3;

[0023] The anti-detachment device 3 includes a U-shaped clamp 31 and a clamp 32. The inner surfaces of the clamps 31 and 32 that contact the connecting rod 1 are rectangular or semi-circular. Both clamps 31 and 32 have locking holes 33 on their bottom sides. After clamps 31 and 32 are mated and fitted onto the connecting rod 1, bolts 34 pass through the locking holes 33 for locking. The top surfaces of clamps 31 and 32 each have movable grooves 35, with mating holes 36 within each groove. Clamp 31 has two locking blocks 37 on its top side, and clamp 32 has two locking grooves 38 on its top side. After clamps 31 and 32 are mated, the two locking blocks 37 and the two locking grooves 38 are connected one-to-one. After docking, the two docking holes 36 are locked together at both ends of the locking strip 6. The side of the U-shaped clamp 1 31 and clamp 2 32 that contacts the connecting rod 1 is provided with a rubber pad. The rubber pad is an adhesive rubber pad or an adhesive silicone pad, which serves as an anti-slip pad. During installation, clamp 1 31 and clamp 2 32 are docked on the outside of the connecting rod 1. At the same time, the two ends of the locking strip 6 on the inclined steel wire rope 4 are docked with the docking holes 36 on clamp 1 31 and clamp 2 32. After clamp 1 31 and clamp 2 32 are docked on the connecting rod 1, the two docking holes 36 and the locking strip 6 are in a movable connection state. Then, the clamp 1 31 and clamp 2 32 are fixedly installed on the connecting rod 1 by the bolt 34 docking with the locking holes 33 at the bottom of clamp 1 31 and clamp 2 32.

[0024] The limiting device 5 includes two threaded grooves 51 and two tightening screws 52. The two threaded grooves 51 are opened at the bottom ends of clamp 1 31 and clamp 2 32, and the two tightening screws 52 are connected one-to-one in the two threaded grooves 51. The two tightening screws 52 are tightened to the flange at the connection between the connecting rod 1 and the traction seat 2. By connecting the tightening screws 52 to the threaded grooves 51 and tightening the inclined steel wire rope 4 to the flange at the connection between the connecting rod 1 and the traction seat 2, the slippage on the connecting rod 1 after clamp 1 31 and clamp 2 32 are mated on the outside of the connecting rod 1 can be avoided.

[0025] The operation steps of this utility model are as follows:

[0026] Two anti-derailment devices 3 are used in pairs. One anti-derailment device 3 is installed near one side of the traction seat 2 and is rotatably connected to one end of the inclined steel wire rope 4. The other end of the inclined steel wire rope 4 is rotatably connected to the car body connecting seat. The other anti-derailment device 3 is installed near the other traction seat 2 and is rotatably connected to one end of the inclined steel wire rope 4. The other end of the inclined steel wire rope 4 is rotatably connected to the bogie connecting seat. By tightening both ends of the connecting rod 1, detachment is prevented, thereby avoiding safety hazards or major safety accidents.

[0027] During installation, clamp 31 and clamp 32 are connected to the outside of connecting rod 1. At the same time, the two ends of the locking strip 6 on the inclined steel wire rope 4 are connected to the connecting holes 36 on clamp 31 and clamp 32. After clamp 31 and clamp 32 are connected to the connecting rod 1, the two connecting holes 36 and the locking strip 6 are in a movable connection state. Then, the bolt 34 is connected to the locking hole 33 at the bottom of clamp 31 and clamp 32 to fix clamp 31 and clamp 32 on the connecting rod 1.

[0028] By connecting the tightening screw 52 to the threaded groove 51 and tightening the flange at the connection between the inclined steel wire rope 4 and the connecting rod 1 and the traction seat 2, the slippage of the clamp 31 and clamp 32 on the connecting rod 1 after they are mated on the outside of the connecting rod 1 can be avoided.
